TYPE FOR PRINTING LAMP-SHADES AND ANALOGOUS ARTICLES.

SPECIFICATION forming part of Letters Patent No. 453,772, dated .T une 9, 1891.

.Application filed August 20, 1890. Serial No. 362,498. (No model.)

To all whom it may concern:

Be it known that I, THOMAS HARPER, a citi- Zen of the United States, and a resident of Testchesten in the county of. IVestchcster and State of New York, have invented certain new and useful Improvements in Type for Printing Lamp-Shades and Analogous Articles, of which the following is a specification.

The object of my improvement is to provide a simple and inexpensive type which will present a substantially flat surface for in king and will yield to adapt itself to the convexity of a lamp-shade or like article.

I will describe a type embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure lis a face view of a type embodying my improvement. Fig. 2 is a sectional side view of the same. Fig. 3 is an end view of a socket comprised in the type, and this view is made to a smaller scale than Figs. I and 2. Fig. a is a front view of a type of modified construction. Fig. is a sectional side view of the type illustrated in Fig. 5.

Similar letters of reference designate corresponding parts in all the figures.

I will first describe the example of the i1nprovement illustrated by Figs. l and 2.

A designates a printing-surface made of sheet-rubber, rubber cloth, or analogous materi al, cut to a shape to represent some article or thing.

B designates a support consisting of a number of round pins or cylinders 1)',iitted together in close contact within a case b2, which may be made of sheet metal. These pins or cylinders may advantageously be made of wood. At the rear 0r inner ends they are fastened by cement or otherwise to a sheet of rubber, rubber cloth, or like material b3, which at the edge is secured to the rear edge. of the case b2. This sheet forms a spring. Normally the pins or cylinders will occupy parallel positions, and the printing-surface will consequently be flat. In this condition it can be properly inked. IVhen pressed against a convex articlesuch as a lamp-shade*the pinsor cylinders will be free to yield independently to allow of the printing-surface adapting itself to the convexity of the article.

Hence this type is capable of producing imprints upon convex surfaces.

The caseb2 is shown as of vertical form and as secured to arms c c2, forming part of a holder C, which comprises a socket D of cylindric form having a longitudinal opening and provided adjacent to the opening with lugs d d2, which may be drawn together by means of a screw d3, which passes loosely through the lug d and engages with a tapped hole in the lug d2. The socket is intended to lit a movable arm R in a press.

In order to insure the iiattening out of the printing-surface, a plate or follower E may be combined with the holder C and support B. This holder, as shown, is of rectangular form, fits between the arms c c2, and is supported by a shank e, which passes into a longitudinal cavity in the arm R. This plate is intended to be moved upward or outward into contact with the sheet b3, preliminarily tothe inking of the printing-press, and upon contacting with said sheet it will bring the ends of the pins or cylinders b into the same plane, if they should have previously occupied any different relation.

The printing-surface A will preferably be fastened only to the center pin or cylinder b. It may be fastened thereto by cement, as at s.

Turning now to Figs. 4 and 5, it will be seen that the printing-surface A is similar to the one in the first-described example of my iinprovement, and that the support I3 for the printing-surface consists of a number of pins or cylinders b fitted in a case b2. In this example of my improvement the pins or cylinders are not, however, arranged in contact with each other, but the case h2 is provided with a number of cavities, and the pins or cylinders are fitted in these cavities so loosely as to be free to slide lengthwise therein. Across the back of the case b2 a sheet of rubber, rubber cloth or like material b3 is extended. This at the edges is fastened to the back of the case. The rear or inner ends of the pins or cylinders rest against this sheet, and may -be secured thereto by cement or otherwise. In front of the case b2 the pins or cylinders are surrounded by helical springs b, which at one end bear against the front or outer side of the case b2, and at the other end IOC are secured to the pins or cylinders-as, for instance, by being driven into the latter. The pins or cylinders cannot be moved inward Without compressing these springs. Vhenever the pressure upon the outer ends of the pins or cylinders is relaxed, the springs Will serve to readj ust the pins or cylinders to their normal position. The case b2 is secured to arms c c2, forming part of a holder C, which is provided with a socket D, like that described in connection With the first example of my improvement.

Preferably the printing-surface Will be secured merely to the center pin. Cement applied, as at s, may serve to secure it in place.

AlfolloWer-E may be Ycombined with the holder C and support B, as in the other eX- ample of my improvement.

It will be seen that the support B is much larger than the printing-surface A. This is to render the employment of larger printingsurfaces possible.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

l. A type having a printing-surface and a support therefor, composed of longitudinallymoving .pins or cylinders, substantially as specified.

2. A type having a printing-surface and a support therefor, compcsed of longitudin llymoving pins orcylinders iittin g within a case, substantially as specied.

3. A type having a printing-surface and a supportltlierefor, composed of longitudinallymoving pins or cylinders fitting Within a case, and a yielding material arranged across the rear or inner ends of said pins or cylinders, substantially as speeied.

4. A type having a printing-surface and a support therefor, composed of longitudinallymoving pins or cylinders fitting Within a case, and springs, one for each pin or cylinder, for holding them normally in parallel positions, substantially as speciiied.

5. A type having a printing-surface and a support therefor, composed of lon oitudinallymoving` pins or cylinders iitting Within a case, springs surrounding said pins on cylinders, and a sheet of material extended across the inner or rear ends of said pins or cylinders, substantially as specified.

G. A type having a printing-surface and a support therefor, composed of longitudinallymoving pins or cylinders fitting Within a case, and a plate or follower arranged adjacent to the rear or inner ends of the pins or cylinders, substantially as specified.

Signed at New York, in the county of New Yorkand State of New York, this 12th day of May, A, D. 1890.
